Hey i dont under stand funtion imports


#1

What do I have to do because I don't understand at all what's happening


#2

Please post a link to the exercise so we can have a look. Thanks.


#3

I think he might have an issue with the import of the square portion of math. I'm having trouble getting it to work myself


#4

The sqrt function is imported from math, as follows:

from math import sqrt

Now in our code we will write,

y = sqrt(x)

where x is the parameter of the function, and y is the return value.

def sigma(sigma_squared):
    return sqrt(sigma_squared)

thank but I figured it out but I need help with this list and slicing
suitcase = ["sunglasses", "hat", "passport", "laptop", "suit", "shoes"]

first = suitcase[0:2] # The first and second items (index zero and one)
middle = suitcase[2:4] # Third and fourth items (index two and three)
last = suitcase[5:6] # The last two items (index four and five)


#6

Not sure how this relates to the opening topic. We could still use a link to the lesson, please.

Your slices look correct. Is there an error message?

last = suitcase[4:]

#7

Oops, try again. It looks like your last slice is ["suit"] instead of ["suit", "shoes"].


#8

oh I got thank you but it had 0-5 and the last two were 4-5
